'ro `ALL'WHOM 1'1 MAY coNoERN:V

Be it known that I, 'GEORGE WnLE'rT, otRichburg` in the county of Alleghany, and State of-New York, hsvejinvented a new and improved Device for Turning Logs on Saw-Mills; and I do hereby declare that the 'following i's a. full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference' being had to th'e accompanying drawings,forming part of this specification.

Figure l-represents a vertical'longitudinalsection of my improved log-turning device. l

Figure 2 is a. vertical transverse section of lthe same.

Similar letters of reference indicatev corresponding parts.

This invention relatesto a'nexv apparatus for revolvingJogs on- `the carriages of circular and other-saw-mills. Its object-istordo away with the jar and shock caused by the ordinary method of turning over the logs.

.My invention consists in the use cfa wheel or wheels on a rotating axle, the edges of said wheels receiving the weight of the log, when the same hasbeen partly turned by` the aid of the ordinary suspended cant-hook, the wheels then carrying the log back to its right place on the carriage, adjusting it, and letting it' down gradually and gently, vso as to avoidull jars and shocks that might injurethe machinery.

'A, in thedravrng, represents the carriage of a san'ingfrnachine; BB are the headblocks. C is a stationary fra-me or bed, a`rranged under'thecurriage, so that the latter moves above it. In the frame C are the bearings for a horizontal shaft, D, on which wheelsE are mounted. 'The axle d is parallel withthe log on the carriage.

On the axle D is also mounted a small pulley, a, towhich the end ot a cord, b, is fastened. This cord `passes over pulleys c e-,to an elevated frame, F, so as to suspend a. hook, d, above the log. When the log is to be turned,the hook is made to catch under it, as in iig. 1. The shaft D'is then revolved, by sui-table mechanism, in the direction of the arrow in iig. 1, andfthereby the cord b is gradually wound around the pulley a; the hook is thereby raised, and ca'nts the log, as sboivn by red lines in ig.`1, so that the log falls upon the roughened edges of the Wheels E, while its one edge rests on the carriage, as indicated,

The wheels, continuing to turn, carry the'log gradually against the head-bloclrs, and :1t-the Sametime gradually lovver the elevated portion of the log until thev same slips entirely olf the Wheels. It is then in the proper position on the carriage.

A'portion of each wheel can be ilattened, asshown, so as not to project above the frame C, to allow the log to be moved to the carriage on the frame.

I claim as new, `and desire to secure by Letters Patent- The described arrangement of the wheels E E, relatively with the head-blocks, operating in connection with the cant-hook to turn the log, as herein shown and described. i
